Technique and system for reducing contamination build-up on fuser roll by reduction of static charge build-up in IGEN3 fuser subsystem

Abstract

A method and system for reducing contamination build-up within a fuser roll system are disclosed. The method and system includes a donor roll in rotational combination with a fuser roll. The donor roll can be configured to transfer a toner release agent to the fuser roll to reduce toner build-up on the surface of the fuser roll. A grounded static brush can be located proximate to the donor roll. The grounded static brush can be configured to inductively remove electrostatic discharge from the surface of the donor roll. The reduced electrostatic reduces contamination build-up on the fuser roll, and therefore increases the cycle life of the components of the fuser roll system.

1. A method of reducing contamination build-up in a fuser roll system comprising:
 providing a donor roll and a fuser roll, wherein the donor roll is in rotational combination with the fuser roll; and 
 reducing contamination on the fuser roll by positioning a grounded static brush to neutralize static charge on a surface of the donor roll, wherein the grounded static brush is positioned with a gap between the static brush and the donor roll. 
 
     
     
       2. The method of  claim 1 , wherein reducing contamination on the fuser roll comprises reducing toner resin, offset, gelled oil, pigment staining, and Zinc Fumarate. 
     
     
       3. The method of  claim 1 , further comprising:
 providing one or more additional grounded static brushes. 
 
     
     
       4. The method of  claim 3 , wherein the one or more additional grounded static brushes are positioned adjacent to the grounded static brush. 
     
     
       5. The method of  claim 3 , further comprising:
 reducing contamination on the fuser roll by positioning the one or more additional grounded static brushes to neutralize static charge on the fuser roll, wherein the one or more additional grounded static brushes are positioned with a gap between the one or more additional grounded static brushes and the fuser roll. 
 
     
     
       6. The method of  claim 1 , further comprising:
 transferring a release agent from the donor roll to the fuser roll. 
 
     
     
       7. The method of  claim 1 , wherein the gap is in a range of about 1-20 millimeters. 
     
     
       8. A fusing system comprising:
 a donor roll in rotational combination with a fuser roll; and 
 a grounded static brush configured to reduce contamination on the fuser roll by neutralizing static charge on a surface of the donor roll, wherein the grounded static brush is positioned with a gap between the grounded static brush and the donor roll. 
 
     
     
       9. The system of  claim 8 , wherein the grounded static brush is further configured to reduce a pigment on the fuser roll by neutralizing the static charge on the surface of the donor roll. 
     
     
       10. The system of  claim 8 , further comprising one or more additional grounded static brushes. 
     
     
       11. The system of  claim 10 , wherein the one or more additional grounded static brushes are positioned adjacent to the grounded static brush. 
     
     
       12. The system of  claim 10 , wherein the one or more additional grounded static brushes are configured to neutralize static charge on a surface of the fuser roll, and wherein the one or more additional grounded static brushes are positioned with a gap between the one or more additional grounded static brushes and the fuser roll. 
     
     
       13. The system of  claim 8 , wherein the donor roll is configured to transfer a release agent to the fuser roll. 
     
     
       14. The system of  claim 8 , wherein the gap is in a range of about 1-20 millimeters. 
     
     
       15. A method of reducing contamination build-up in a fuser roll system comprising:
 receiving a toner release agent onto a donor roll in rotational combination with a fuser roll; 
 transferring the toner release agent from the donor roll to the fuser roll; 
 reducing contamination on the fuser roll by positioning a grounded static brush to neutralize static charge on a surface of the donor roll, wherein the grounded static brush is positioned with a gap between the grounded static brush and the donor roll. 
 
     
     
       16. The method of  claim 15 , wherein reducing contamination on the fuser roll comprises reducing a pigment on the fuser roll. 
     
     
       17. The method of  claim 15 , wherein one or more additional grounded static brushes are positioned with a gap between the one or more additional grounded static brushes and the donor roll. 
     
     
       18. The method of  claim 15 , wherein the toner release agent is organomodified silicone oil. 
     
     
       19. The method of  claim 15 , wherein the gap is in a range of about 1-20 millimeters. 
     
     
       20. The method of  claim 15 , wherein the donor roll receives the toner release agent from a metering roll.
